Abstract

The invention relates to a system and method for calibrating marine biaxial tilt sensor. The system comprises the following parts: a reading unit, which is in communication connection with a marine biaxial tilt sensor and used for reading the output voltage of the tilt sensor at the standard level; a storage unit, which is used for storing the output voltage read by the reading unit; a calibration unit, which is used for reading the actual output voltage of the marine biaxial tilt sensor in actual measurement, and eliminating errors in the actual measurement by combining with the output voltage in a memory cell, so as to calculate the actual acceleration; and an angle calculating unit, which is used for calculating the actual angle based on the actual acceleration. The obtained standard output voltage of the marine biaxial tilt sensor on the standard level is used for eliminating the errors generated in the actual measurement of the marine biaxial tilt sensor, so that the angle measured by the tilt sensor coincides with the actual inclination angle, and the measurement accuracy of the tilt sensor is improved.

Description

technical field [0001] The invention relates to the calibration of a marine dual-axis inclination sensor, in particular to a calibration method and system for a marine dual-axis inclination sensor. Background technique [0002] The marine dual-axis inclination sensor is used to measure the inclination angle of the two disposal directions of the horizontal plane relative to the horizontal plane. The inclination angle is measured by two vertical inclination sensors on the marine dual-axis inclination sensor. Since the inclination sensor itself, the measurement circuit itself, and the welding position will all be There is an inherent deviation, so that there is an error between the tilt angle measured by the tilt sensor and the actual tilt angle, and the accuracy is low. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a calibration method and system for a marine dual-axis inclination generator, and s...
